Specification of Iietters Patent.

'Patented Apr. i, 1913.

Application filed June 5, 1911. Serial No. 631,275.

To H 'io/om t may concer/1t Be it known that I, Gus'rAvii tl. MARTEL, acitizen of the United States, and a resident of the city of Chicago,county of Cook, and State of Illinois, have invented certain. new anduseful Improvements in Tire-Patcliing Devices, of which the following isa specilication.

rlhis invention relates to improvements in patching` devices forpneumatic tires and the object of this invention is to provide a deviceof this character which shall be of ex tremely simple construction,hence of low cost to manufacture, and also a device which may be readilyand expeditiously applied to a tire or removed therefrom; and further, apatching device which will be of great eiiiciency in use.

Other objects will appear hereinafter.

`With these objects in view' my invention consists in the tire patchingconstruction which will be hereinafter described and more particularlypointed out in the ape pended claim.

My invention will be more readily understood by reference to theaccompanying drawings forming a part of this specification` and inwhich,

Figure 1 is a side elevation of a fragment of a pneumatic tire and rimto which is applied a patching device embodying my invention, Fig. 2 isa transverse section talren on line .a-m of 1, Fig. 3 is a fragmentarysectional detail taken on substantially line .f1/ y of Fig. 1, and Fig.4 is a detail perspcctive of one of the securing` hook members embodiedin the invention, detached.

Referring now to the drawings I have illustrated therein the usualclencher rim 1 having the engaging or clenching flanges 2 at itsrespective edges. Mounted upon the rim 1 is a pneumatic tire 3 ofordinary type, said tire being secured in position on said rim by meansof the iianges 2 in the usual manner. Arranged about the tread portionof the tire 3 is the patching strap 4 which is formed of any suitable,durable, flexible material, leather or raw hide being preferablyemployed. rlhe strap 4 may be of any width desired so as to adapt thesame` to effectually serve the purpose for which it is designed, saidstrap being of a length such that when the same is arranged about thetire, with the latter in inflated condition,

said strap will extend substantially from one of the flanges 2 to theother, as clearly shown in Fig. 2. Arranged at the respectiveextremities of the strap 4 are similar bars or yolres 5 which aresecured rigidly in position by means of screws 6 and nuts 7. Said bars 5are of bowed form to conform with the curvature of the rim, the inner orunder sides of said bars being shaped to conform with the conformationof the adjacent surfaces of the rim flanges 2. Also, it will beobserved, that the bars 5 are so formed that when arranged in operativeposition upon the outer sides of the flanges 2 the portions thereof towhich the extremities of the strap 4 are secured are disposedsubstantially parallel with the adjacent sides of the tire 3 and so thatthe ends of the strap 4 will be held in snug engagement with theadjacent surfaces of said tire.

The bars 5 and hence the strap 4 are secured in operative position bymeans of hook members 8 the inner ends of which are adapted to engageover the inner edges of the engaging iianges 2, as clearly shown in Fig.2. The hooks S are provided with outwardly projecting threaded shanlrs 9which loosely engage perforations 10 formed for the reception thereof inthe bars 5. Nuts 11 threaded upon the outer ends of the Shanks 9 serveevidently to secure the bars 5 in operative position. nut-locks 12 ofany approved design being preferably employed in order to lock said nutsin position. In attaching the tire patch it is required that the tire befirst deflated. With the tire in deflated condition, the hook members Smay readily be arranged in engagement with the flanges 2. When saidmembers 8 are so arranged the strap 4 is placed upon the tire and thebars 5 at the extremities thereof slid to position upon the outwardlyprojecting shrinks 9 of the hooks 8. This being done the nut-locks 12and the nuts 11 are then arranged in position thereby completing thesteps necessary for attaching the device. fter the latter has beenarranged as described the tire is inated, the strap 4, upon suchinflation. being tightened about the tire because of the expansion ofthe latter, serving to eifectually reinforce said tire at the place ofapplication. Should the strap 4 stretch so that the same no longersnugly fits the tire, one of the bars 5 may be removed and said strapshortened to the proper length and the bar 5 resecured.

A tire patching device as set forth is of extremely economicalconstruction hence may be manufactured at a lovv cost, the same beingadapted when applied to a tire to effectually serve to strengthen thesame.

While I have illustrated and described the preferred construction forcarrying my invention into effect, I do not Wish to be limited theretoas there might be various changes made in the details of constructionand the arrangements of parts Without departing` from the spirit of theinvention as comprehended within the scope of the appended claim.

Having described my invention What I claim as new and desire to secureby Letters Patent is:

In a tire patching device, the combination of a flexible patching strap;angular yokes having one leg secured to the ends of said strap, theother leg being curved to lit a rim fla-nge; securing hooks adapted toengage rim flanges and having threaded shanks eX- tending through saidyokes; and nuts on said Shanks, substantially as described.

In testimony whereof I have signed my Y name to this specification inthe presence of two subscribing Witnesses.
